Winterizing Class A

[Toolguy]

First time winterizing my Motorhome. My question is how should i leave gas tank. I am thinking i should fill the tank. Do i need to add something to the tank? If so what and how much?

Thanks

I personally fill the gas/diesel tank. For diesel owners, consider a biocide additive such as this.

You have a gas coach with the 7.3 V-8, so I would recommend that you fill the gas tank, & just before doing so, add 2 cans of "Sea-Foam", which will preclude any moisture.
This is what I did each year when I had to "winterize", and it worked perfectly.
Moving to Florida, I do not have to winterize, but just keep driving!

I use one gallon of Seafoam in 80 gal of gasoline.
